SPECIFICATION forming part of Letters Patent No. 709,443, dated September 16, 1902.

Application filed November 20, 1901. Serial No. 82,994. (No model.)

Q tu whom, t may concern,.-

Be it known that WASHINGTON H. STEW- ART, deceased,` formerly a citizen of the United States, and a resident of San Jose, in

the county of Santa Clara and State of Oalifornia, did during his lifetime invent a new and useful Hydrocarbon-Burner, of which the following is a specification.

This invention relates to hyd rocarbon-bn rn- Io ers, the object in View being to provide a simple, effective, and reliable `burner for the vaporization and burning of all grades of oil from gasolene to the heaviest of crude oils or petroleum. The construction of the burner x5 is such that the `oil is thoroughly disintegrated or atomized, vaporized, and mixed with steam preparatory toburning the same, the burner as a Whole consisting of a vaporizer embodying an atomizing and mixingl iiecting-block against which the combined oil i .zo chamberin which is placed a deiector or dej .and steam is projected with suticient force I t0 thoroughly atomize the eiland mix it with oil, converting it into a gas or vapor which upon arriving at the tip of the burner ignites and is consumed practically Without smoke or residue in the form of carbon or soot. In `combining the burner with a furnace or other heater the vaporizer is preferably located eX- teriorly of the furnace or heater, while the tip of the burner is arranged Within the same 4o at any advantageous point.

With the above and other objects in view i the invention consists inthe novel construction, combination,and arrangement of parts hereinafter fully described, illustrated, and Y other end byan adjustable stop 15 inthe form 95 claimed.

In the accompanying drawings, Figure 1 is aside elevation'of a hydrocarbon-burner coni strucied in accordance with the present in- 'vention. Fig. 2 is a centrallongitudinal sec- 5o tion through the same. Fig. 3 is an enlarged central longitudinal section, through the Vsteam-chamber and adjacent parts. Fig. A1

is a detail perspective view of the hand adjusting device for the oil-inlet or introduction valve.

Like 'reference-numerals designate correspending.Y parts in all the figures of the draw- INES.

Referring to the drawings, 1 designates a spherical atomizing and mixing chamber in 6o which is arranged an adjustable and reversible deflector or dei'lecting-block 2, having one concave side 3 and one convex side 4, either of which may be presented to the incoming steam and oil. The deiiector-2 is lo- 65 cated directly opposite the steam `and oil nozzle 5 and is removably mounted upon one end of an adjusting-stem 6,4 which is threaded, as shown at 7, and inserted through a threaded opening 8 in a screw-plug 9, .fitted 7o into the end of the vaporizing-chainber, hereinafter described, said stem being provided with a handle 10 preferably in the form of a wheel, by means of which the stem may be turned for adjusting the same inward and 75 outward and varying the distance between the' deiiector 2 and nozzle 5. When adjust ed, the stem may be fiXedly secured bymeans of a jam-nut 11.

The atomizing-chamber lis provided at one 8o side with a cylindrical extension 12, forming the vaporizing-chamber. Said chamber is practically filled with a compact maze 13, Which preferably consists of closely laid or wrapped meshed Wire, Wire-cloth, or 'other 85 similar material the density 0f which is pri:- marily regulated by the nature or quality of the oil in connection with which the burner is to be subsequently used. The maze encirclesthe delector-stem 6, but does not inter- 9o fere with the longitudinal movement .of said stem, said maze being supported at one end by an inwardly-extending annular iange 1e adjacent to the atomizing-chamber andlat its of la tube extending around the stem 6 and having one end threaded into a socket 16 in the plug 9, thus enabling the tubular stop to be adjusted to bring its projecting end to bear properly against the lmaze 13. The entire ice vaporizer, together with the nozzle 5 and the valves leadingto and controlling said nozzle, as Well as the oil-chamber hereinafter described, are inclosed in an outer jacket 17,

within which sufficient space is left to place a filling 18 of some suitable non-conducting material, such as asbestos, which will prevent l 20, preferably in the form of a hollow sphere,`

said chamber being connected with the vaporizing chamber by means of a nipple 21 screwed into a pendent extension of the vaporizing-chamber,as clearly shown in Fig;2. Said waste-chamber 2O is designed ,to receive and catch any particles of unvaporized oil or other material in starting the burner and before the vaporizer becomes thoroughly effective by reason of low steam-pressure. This pre- Ventsthe oil from being carried to the tip of the burner, which would tend to clog the tip. The waste oil and other material passing downward to the waste or condensation chamber 20 may be withdrawn by means of a drawoif cock 22 or may be discharged into a pipe 23, which may be led back to the oil-reservoir.

The oil introduction orinlet valve 24 is in the form of a hollow cylinder the discharge end of which is contracted in conical form, 'as shown in Fig. 2, so as to properly seat itself against the valve-seat 25, formed by the conical inner surface of the nozzle 5. Said nozzle 5 is extended tok form a cylindrical valve-casing 2b', which is eXteriorly threaded and screwed into a cylindrical boss 26, forming an extension of the atomizing-chamber 1 and arranged opposite the Vaporizingchamber 12. Connected with the outer end of the valvechamber 26 is a cylindrical steam-chamber 27, flanged to t into the valve-chamber and connected therewith by means of a threaded sleeve or coupling 2S, suitable packing 29 being interposed between the chambers 26 and 27 to prevent the escape of steam. The outer end of the steam-chamber 27 is enlarged and interiorly threaded to receive a screw-plug 30, which closes that end of the steam-chamber. The plug 30 is provided with a central boss 3l, upon which is rotatably mounted a hand-wheel 32, which is connected with the oil-inlet valve 24 in such manner as to enable said Valve to be adjusted thereby. In accomplishing this result the vcentral portion of the hand-wheel 32is provided with slotted spiral Wings or cams 33, as shown in Fig. 4, the slots 34 thereof, which are concentric with the axis of movement of the wheel, receiving headed studs 35, which are connected with parallel arms 36, extending outward from the enlarged end of the cylindrical portion of the oil-inlet Valve 24, the said portion of the valve being enlarged, as shown at 37, within the steam-chamber, at which point said cylindrical portion of the valve is provided with steam-ports 38, through which the steam passes from the steam-chamber to the inside of the cylinder and thence to the lvalve. The arms 36 pass through openings 39 in the plug 30, and also through small screw-plugs 40, inserted in recesses 4l in the plug coincident With the openings 39, suitable packing 42 being introduced behind the plugs 40 to make a steam-tight fit. The boss 3l is exteriorly threaded to receive4 a dust-guard nut 43, which prevents dust, dirt, and foreign matter from getting access to the fittings, and said nut 43 is backed up by a jam-nut 44, which acts to lock the dustguard nut 43. In order to facilitate the adjustment of the oil-inlet valve, the handwheel 32 is provided with a pointer or indicator 45, 4which moves over graduations 46, represented on the outer surface of the steamchamber, as shown in Fig. 1. In this way the supply of oilmay be very accurately regulated.

Within the cylindrical portion of the oilinlet Valve is arranged a'stem 47, the inner ,end of which is tapered in conical form and Aconstitutes the steam-supply valve,said valve Working against the conical inner surface of the oil-introduction valve 24, as shown in Fig. 2. The outer Vend of said stem is threaded and screwed into and through the plug 30, so

as to admit of the longitudinal adjustment of the stem 47, the stem and valve being operated by means of a handle 48, preferably in the form of a wheel, as shown. At the point where the stem 47 enters the plug 30 there is arranged a packing or stufing boX 49.

50 represents the steam-supply pipe leading into the steam-chamber 27, and 51 indicates the oil-supply pipe which leads into the oil-chamber 52, comprised by the nozzle 5 and cylindrical portion of the oil-inlet valve 24.

The stem 47 is provided with a vplurality of radially-extending Wings 53 of equal length, which serve to center the stem within the cylindrical portion of the oil-inlet Valve 24, while the valve 24 is centered within the oilehamber by means of one or more inwardlyextending annular fianges 54 within the oilchamber. y

The hand-Wheel`32 is provided inits inner face with an annular groove 55, which receives a corresponding annular {iange 56 on the adjacent end of the steam-chamber,thus' giving the hand-wheel a bearing and seat against the steam-chamber.

57 represents the pipe leading to the burnertip 5S, at whichv point the gas or vapor is ignited and consumed.

In order to accurately adjust the steam-inlet valve, the stem 47 is graduated near its outer end, as shown in Figs. l and 2, the stuing-box 49 acting as a pointer or indicator in connection with said graduations to visually indicate the extent to which the steam-inlet valve is opened or closed.

In operation the oil admitted through the pipe 51 Hows into the oil-chamber 52 under IIO sufficient pressure to force it through the nozzle 5 into the atomizing-chamber, thequantity of oil being regulated by the adjustment of the valve 24, which is accomplished by means of the hand-Wheel 32. The pointer visually indicates the position of the valve and the consequent supply of oil delivered through the discharge-nozzle. At the same time steam is admitted through the pipe 50, Apassing into the steam chamber 27 and through the ports 3S to the inside of the valve 24, Where it is discharged into the oil-chamr ber immediately adjacent to the dischargeopening of the nozzle. At this point the oi'l and steam are mixed, the oil being taken up by the steam and forced with considerable pressure against the deflector. The oil is thus dashed into atoms, which are directed or diverted by the concave or con Vex surface of the deiiector, according to whichside is presented toward the nozzle. When the mixed oil and steam strikes against the concave su rface of the deflector, the atoms are thrown backward against the inner surface of the spherical atomizing-chamber, which operates in turn to again deflect the atoms, which are then caught up by the inflowiimT steam and oil and carried with considerable force to ward and into the maze. In case the convex side of the del-lector is placed toward the nozzle 5 the oil and steam are directed outward radially against the inner surface of the atomizing-chamber and then forced forward into the maze, the latter operation being preferable When certain grades of oil` are used. Thus the oil is thoroughly atomized, mixed with steam, and forced by the steam through the maze 13, which completes the process of thoroughly disintegratingthe oil and conpasses out of the vaporizingchamber through the pipe 57 to the tip of the burner, where it is ignited and consumed practically Without residue. Any nnvaporized oil Which finds its Way through the maze dro ps into the Waste or condensation chamber 20, from which it may be drawn off or conducted back to the oil tank orrreservoir. By meanslof the drawo cock 22 steam in case of an emergency may be directed into the oil tank or reservoir.

The chief advantages of the present invention reside in the maze, its construction and arrangement, the mixing-chamber in connection With the adjustable and reversible deiiector, the arrangement, construction, and operation of the valves which control the admission of oil and steam to the mixing-chamber, and the location of the Waste or residue chamber. A most important advantage is obtained by the construction of the oil-chamber and the relation of the steam-conduit and oil-supply Valve thereto, it being apparent, in View of the description and illustration, that the oil j ust preparatory to its escape from the nozzle 5 is spread out in a thin annular layer and at the same time heated to a high temperature before it is finally discharged into the mixing-chamber and thrown against the deflector. The feature just referred to greatly facilitates the disintegration and Vaporization ofthe oil.

It will of course be understood that the l.
